Description of key information

Under the conditions of the study, there was no flash point for the test material up to 110.3 °C when the correction for atmospheric pressure was applied.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
110.3 °C

Additional information

The flash point of the test material was investigated in a study which was performed under GLP conditions and in accordance with the standardised guidelines EU method A.9. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

The test material (nominally 2 mL) was introduced into the test chamber which was then closed. A preliminary measurement was carried out as a rangefinder. The range finder employed the rapid equilibrium mode, starting at 5.4 °C and increasing in 10 °C increments, with a 1 minute equilibration time, until a flash was observed or 110 °C was reached. As no flash was seen up to 110 °C (110.3 °C corrected for atmospheric pressure) in the rangefinder test the definitive test was just carried out at 110 °C with a 1 minute equilibration time. The procedure was done

in duplicate. Instrument operation was verified using a reference substance which has a certified flash point of 74.5 ± 2 °C. Two definitive tests on two different samples established that there was no flash point for the test material up to 110 °C (110.3 °C corrected for atmospheric pressure) when the correction for atmospheric pressure was applied.
